There are several outstanding programs around that can do this sort of 
thing, but before sending you on a hunt for something that isn't what you need:

What coil design/performance information do you need?  L? loss? coupling?

How accurately do you need the numbers? (10% good enough, or do you need 
sub 1% accuracy?)

Is the coil closewound or spacewound (makes a difference in the amount of 
"proximity effect"
for Rac... if the turns are spaced >5 times wire diameter, you can probably 
ignore proximity effect and just use skin effect)
